28.3LPM Online Particle Counter
OPC-6510

The cleanroom remote online particle counter OPC-6510 adopts the principle of optical scattering, which can accurately detect and calculate the number of suspended particles of different particle sizes in the air per unit volume. The gas sampling rate of large flow can simultaneously output the particle number of 5 channels of >0.3μm, >0.5μm, >1.0μm, >5.0μm, >10μm (pcs/28.3L).
